Find the mean, median, and mode of the data, if possible. If any of these measures cannot be found or a measure does not represent the center of the data, explain why.
A sample of seven admission test scores for a professional school are listed below.
11.3, 9.9, 9.6, 11.5, 9.6, 11.2, 10.6
The mean is 12.28
The mode is 9.6.
The median is 10.25.
What is the median, median and mode?Mean, median, and mode are measures of central tendency. Mean is the average of a set of numbers. Median is the number that is at the center of a dataset when the dataset is arranged in ascending or descending order. Mode is the number that occurs most frequently in a dataset.
Mean = sum of numbers / total number
(11.3 + 9.9 + 9.6 + 11.5 +9.6 + 11.2 + 10.6) / 6
= 73.7 / 6
= 12.28
The number that occurs most frequently is 9.6. It occurs twice in the dataset. 9.6 is the mode.
The median = (total number + 1) / 2
(6 + 1) / 2
= 7/2 = 3.5 digit
9.6, 9.6, 9.9, 10.6, 11.2, 11.3
(9.9 + 10.6) / 2
= 20.5 / 2 = 10.25

What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
The original length of the square garage is 19.1 ft.
The length of the new garage is 23.4 ft and the percentage increase in length is 81.6 %.
How to find original land new length of the square garage?Yossi used to have a square garage with 364ft of floor space.
Recently, built an addition to it.
The garage is still a square, but now it has 50% more floor space
Therefore,
area of a square = l²
where
l = side lengthTherefore,
364 = l²
l = √364
l = 19.0787840283
l = 19.1 ft
Therefore, the original length of the square garage is 19.1 ft.
After 50% increase in the area,
New area = 50 / 100(364) + 364
New area = 546 ft²
Therefore,
546 = l²
l = √546
l = 23.3666428911
l = 23.4 ft
Hence,
percentage increase in length = 19.1 / 23.4 × 100
percentage increase in length = 1910 / 23.4
percentage increase in length = 81.6239316239
percentage increase in length = 81. 6 %
Therefore, the length of the new garage is 23.4 ft and the percentage increase in length is 81.6 %.

the point (3, 5) is on the graph of the function f, then the point (x, y) =
is on the graph of F-1.
let me give you a mouthful of something
the domain of f(x) is the range of its inverse, or namely the domain of f(x) is the same set as the range of f⁻¹(x), so for any (a , b) pair on the domain of f(x), there's a (b , a) on the range of f⁻¹(x).
now, that's a bit of of a mumble, but in short it means, if f(x) has a point of (3 , 5), then the graph of f⁻¹(x) has a point which is the same pair but flipped sideways, namely (5 , 3).
that's pretty much true for any function that has an inverse.
Brandon and Kevin both made the All-State Basketball team. Brandon averaged 21.25 points per game in 16 games. Kevin averaged 20.5 points per game in 18 games.
How many more total points did Kevin score than Brandon?
Kelvin score 29 points in All-State Basketball team more than Brandon.
We are given that
Brandon averaged 21.25 points per game in 16 games which means that the mean of points made by Brandon in All-State Basketball team of 16 matches is 21.25
So, the total points made by Brandon is
21.25 × 16 = 340
Kelvin averaged 20.5 points per game in 18 games which means that the mean of points made by Kelvin in All-State Basketball team of 18 matches is 20.5
So, the total points made by Kelvin is
20.5 × 18 = 369

solve system of equations by using elimination method. (solve for (x,y,z) please explain the steps im so confused.
4x-y-2z=-8
-2x+4z=-4
x+2y=6
The solutions of the system of equations are:
x = -2, y = 4, z = -2
How to solve a system of equations by the elimination method?
Here we have the system of equations:
4x - y - 2z = -8
-2x + 4z = -4
x + 2y = 6
To eliminate one variable, we can add the second equation and two times the third equation, we will get:
(-2x + 4z) + 2*(x + 2y) = -4 + 2*6
Now we can simplify that so we get:
4z + 4y = -4 + 12
4*(z + y) = 8
z + y = 8/4 =2
z + y = 2
With that we can write z in terms of y.
z = 2 - y
And with the third equation we can write x in terms of y.
x = 6 - 2y
Replacing that in the first equation we get:
4*(6 - 2y) - y - 2*(2 - y) = -8
Now we can solve this for y.
24 - 8y - y +2y - 4 = -8
20 - 11y = -8
-7y = -28
y = 28/7 = 4
Now that we know the value of y we can find the values of x and z.
x = 6 - 2y = 6 - 2*4 = -2
z = 2 - y = 2 - 4 = -2
The solutions of the system of equations are:
x = -2, y = 4, z = -2

Step-by-step explanation:
17/18 and 11/12
First find the LCM, least common multiple, of the denominators 18 and 12.
In order to do that, list the factors of 18 and 12 and find the least common factors of them excluding 1.
18: 1, 2, 3, 6, 9, 18
12: 1, 2, 3, 4, 6, 12
Notice any common small factors? Yes they are 2 and 3. Now, multiply them with 18 and 12.
18*2=36
12*3=36
Hence, LCM is 36.
17/18=(17*2)/(18*2)=34/36
11/12=(11*3)/(12*3)=33/36
ginny wants to join a local dance club that has dance events every.there are two memberships options avaiable

What is the complete question?The complete question is given as follows:
"Ginny wants to join a local dance club that has dance events every week. There are two membership options available: Ginny may become a premier member by paying a fee of $150 per year and attend an unlimited number of dances. Ginny may become a regular member by paying a fee of $50 and then pay $8 per dance she attends. How many dances must Ginny attend such that becoming a premier member will cost less than becoming a regular member? "
What is a linear function?A linear function is modeled in slope-intercept form by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The flat fee is the intercept.The cost per dance is the slope.Hence the functions for each option are given as follows:
P(x) = 150.R(x) = 50 + 8x.Being a premier member will cost less when:
P(x) < R(x).
Hence:
150 < 50 + 8x
8x > 100
x > 100/8
x > 12.5 -> at least 13 events.
